Abstract
The present invention relates to a molding method for a flexible honeycomb product. The method is characterized by comprising the following steps: (1) providing a concavo-convex mold, and adopting the concave-convex mold to press a flexible thin layer material, such as aramid fiber paper; (2) maintaining a temperature of 140-180 DEG C for 1-2 hours to carry out shaping; (3) coating an adhesive on the shaped flexible thin layer material, carrying out superimposing, curing, adhesive bonding and molding on the profiling mold, and impregnating in a resin at a temperature of 120 DEG C to carry out curing. With the flexible honeycomb product prepared by using the molding method of the present invention, a sandwich can be made into a curved surface honeycomb product without slitting and splicing, and honeycomb sandwich nodes do not crack, such that uniformity and consistency of the honeycomb product sandwich can be ensured; and the curved surface honeycomb product prepared by the method of the present invention has characteristics of stable appearance, high strength, and good quality.
Description
Technical field
The present invention relates to a kind of forming method, particularly relate to the forming method of flexible honeycomb goods.
Background technology
As everyone knows, honeycomb composite product uses more and more widely because it has in light weight, excellent characteristics such as intensity is high, good rigidly in recent years, and the different aspect materials and the various combination of honeycomb pass produce difform cellular sandwich material.
Making the fundamental method of cellular sandwich is pulling method; The hexagon honeycomb of processing with pulling method can only molding flat or the little cylinder honeycomb article of curvature; During with its moulding large curved surface and hyperboloid honeycomb article; Just need cut and splice manufacturing, this has intangibly increased technology difficulty, also can't guarantee the quality of honeycomb products.
Summary of the invention
The purpose of this invention is to provide and a kind ofly be used to make that dimensional stability, intensity are high, the forming method of the flexible honeycomb goods of the measured curved surface honeycomb article of matter.
For solving the problems of the technologies described above, the present invention takes following technical scheme: a kind of forming method of flexible honeycomb goods is characterized in that: may further comprise the steps:
(1) a kind of male and female mold is provided, utilizes said male and female mold to push down the flexible thin material, like aramid fiber paper;
(2) under the 140-180 degree, keep 1-2 hour with typing;
(3) gluing on the flexible thin material after the typing glueds joint moulding with the superimposed curing of pattern, the resin solidification that dipping 120 degree solidify.
Further, the flexible thin material among the said step (1) handles through following: flood said flexible thin material with liquid phenolic resin earlier, and make its semi-solid preparation.
Further, the proportion of said phenolic resins is 0.94g/ml.
Further, the temperature of said semi-solid preparation is 120 degree.
Further, said flexible thin material is an aramid fiber paper.
Use the made flexible honeycomb goods that make of forming method described in the present invention when sandwich is made into the curved surface honeycomb article; Need not cut splicing; And the cellular sandwich node does not ftracture; Thereby can guarantee the uniformity and the uniformity of honeycomb article sandwich, the curved surface honeycomb article of being processed by said method has dimensional stability, high, the measured characteristics of matter of intensity.
Description of drawings
Fig. 1 is the structure and the working state schematic representation of the male and female mold among the present invention.
The specific embodiment
Be elaborated in the face of technical scheme of the present invention down.
The forming method of said flexible honeycomb goods may further comprise the steps:

(2) under the 140-180 degree, keep 1-2 hour with typing;
(3) gluing on the flexible thin material after the typing glueds joint moulding with the superimposed curing of pattern, the resin solidification that dipping 120 degree solidify.
Preferably, the flexible thin material among the said step (1) handles through following: flood said flexible thin material with liquid phenolic resin earlier, and make its semi-solid preparation.Preferably, the proportion of said phenolic resins is 0.94g/ml.Preferably, the temperature of said semi-solid preparation is 120 degree.
Preferably, said flexible thin material is an aramid fiber paper.
Be elaborated in the face of said male and female mold down:
Fig. 1 shows the structure and the working state schematic representation of the shaped device of the flexible honeycomb sandwich among the present invention.
As shown in Figure 1, said shaped device comprises first mould 1 and second mould 2.Said first mould 1 is provided with a plurality of first convexities 3 and a plurality of second convexities 4, the said first protruding 3 and second protruding 4 compartment of terrain setting successively, and preferably, said first protruding 3 height is greater than the height of said second convexity 4.Said second mould 2 is provided with from individual first recess 5 and a plurality of second recesses 6, and said first recess 5 and second recess 6 compartment of terrain successively are provided with, and preferably, the cup depth of said first recess 5 is greater than the cup depth of said second recess 6.
At each constantly; First and/or second recess of at least one said second mould that first and/or second convexity of at least one said first mould is corresponding with it respectively contacts engagement typely, so that will place the flexible thin material's moulding agley between the said corresponding part that contacts between said first mould 1 and second mould 2 engagement typely.Said when contacting when breaking away between said first mould and second mould, said flexible thin material relies on the plasticity of himself to keep shape agley engagement typely.
Preferably, said first, second convexity has the surface of the crest shape that is slick and sly, and first, second recess has the surface of the trough shape that is slick and sly.Further, preferably, said first, second raised surface matches with the surface of said first, second recess.Preferably, the surface of said crest shape and/or trough shape can be sine wave, parabola, involute, hyperbola formula curved surface, also can be the curved surface with other predetermined form.Preferably, the surface of the surface of said crest shape and trough shape can select multi-form curved surface combined from above-mentioned various forms of curved surfaces.
Preferably, be provided with at least 2 second convexities between per two first convexities in said first mould, preferably, be provided with 2 second convexities.Preferably, at least two second protruding height between per two said first convexities can be identical, also can be different.
